Fig. l2 is a plan showing the bent plate of the n stopping device.

Fig. 13 is a side elevation partly in sectionr showing the mounting of the rocking bar.

As shown on the drawings, pillars 3 supporting a horizontal beam 2 divide the machine frame I into two independent parts, accommodating two separate reeling pan tables 4 and 5. The main axle 3 is horizontally supported by the pillars 3 and on one end of the axle 3, a belt pulley 1 is provided and by means of belt 3 is made to cooperate with pulley 3. One end of the axle I3 of the pulley 3 is introducedinto the inside of gear box Ii and is fixed to bevel wheel I2 meshing with a bevel wheel I3 which is fixed to shafting I4.

As shown on Fig. 4 and Fig. 5, a friction ring I5 is loosely fittedA to shaft I4; and one edge of the friction ring I5 is engaged with lthe fiat face ofwheel I3; the axle I1 of the wheel I3 being supported at both ends by the walls of gear box I.

On one end of axle /|1, 4a. spring I3 is provided which tends to press it against fric- ;tion wheel I3. Underneath ax1e |4 a threaded (rod |3 is provided, one end of which ispmade to project out to the outside of the gear box II, and

terminates in a handle 20. On the other end of the rod I9 the bottom portion of bar 2| is screw threaded.

'I'he upper portion of the rod 2| is forked to embrace the shafting I4 between rings 22 and 23 so'as to be easily removable, the ring 22 be= ing connected with the friction ring I5.

` When the handle 20 is operated and the rod I9 is rotated, the rod 2| moves with it and the friction'ring I5 also moves along the shaft I4, thus changing its contact point with wheel I8 and regulating the speed of the wheel I6 accordingly.

On the other end of the axle I1, a worm gear 24 is fixed and a worm gear -25 engaging with it. is fixed to a longitudinal axle 28. A worm gear 23 fixed to spool .axle 21 engages the worm gear Thus, the rotation of axle I4 is transmitted to axle 234and axle 21; these movements of the axles are independently transmitted to the reeling portions. 'I'he other end of axle 21 is simply supported in the gear box 29 of the adjacent reeling machine.

On the other end of shafting I4 a construction similar tovthat above described is provided and in that way, several multi-spool reeling machines are continuously installed side by side.

To the axle. 23, (Fig. 6), a toothed wheel 30 is fixed below the worm gear 23, which wheelis made to engage with-another toothed wheel 3|. To the axle 32 of toothed wheel 3|, a roller 33 is eccentrically fixed and embraced by semi-circular arm pieces fitted on topv of an operating axle 34. A sustaining arm 33 at the lower end of the axle 34 is fixed to circular ring 31 to which a circular plate 33 is attached.

'I'he lower portion of the vertical' axle 23 is passed through the lcircular ring 31 and at its lower end, an eccentric plate 33 is fixed. 0n one side of eccentric plate 39 a pin 40 is fixed and its upper portion is inserted in an oval hole 4| drilled in one side of the circular plate 33.

At the lower portion of and on the other side of the circular plate 33, an arm 42 is fixed, to

which a connecting bar 43 is fastened.

` The other end of the bar 43 is connected to rocking bar 44. 4 y

'I'he rocking bar 44 is provided under the rows of spools and as shown in Fig. 13, both edges |54 are bent into arcuate form and made to be resilient.

l A metal line 43 is enclosed by these edges, which latter embrace drum shaped rollers |33 provided in front of the horizontal beam 2.

Thread guides 46 are provided at regular intervals and secured to the bar 44 by brackets |58. Thus, accompanying rotation of the axle 26, the eccentric plate 39 also rotates; and by means of the pin 46, the circular plate 38 rotates, causing the reciprocating motion of rocking bar 44. At the same time, by means of the toothed wheel 36 and the .wheel 3| the roller 33 rotates and through the axle 34 the circular plate 38 moves; thus by double action of the eccentric plate 39 and the roller 33, the rocking bar slightly makes sidewise motion simultaneously with longitudinal reciprocating motion.

The above mentioned spool axle 21 is provided on one side of the horizontal beam 2 but on the corresponding other side, an independently working axle 41 is provided and to each of these axles 21 and 41, 15 to 30 spools 48 are attached.

As shown in Fig. '7 and Fig. 8, these spools are frusto-conical shaped and through both end plates 49 and 56, axle holes 5| are formed, through which an axle tube 52 loosely fits. On

. the ends of the axle tube 52, circular flanges 53 are formed, so as to prevent the tubular axle from slipping oil.

On end plates 49 and 56, several reinforcing pieces 54 are formed and at this portion, spools 48 areA arranged' and regulated in their positions.

Near the inner end of each reinforcing piece 54 projections 55 are formed and prevent the threads detached from spool 48 from winding around the axle 52 and makes it convenient for removing them.

'I'hese spools 48 loosely ilt on axles 21 and 41 and revolve with the axle by friction.

Thespools 48 are constructed of light metal, such as aluminium and coated with corrosion resisting material, so as to make them proof against acid, oil and alkalinity.

Thus. the spools through the thread guides 46 of the rocking bar 44, take up threads coming up from cocoons and wind them.

As shown on Fig. 1, Fig. 2 and Fig. 3, the thread reeling pans 4 and 5 for receiving cocoons, are rectangular-shaped.

In the backwardportion of each pan, a water tank 56 is provided and by means of partition wall 51, hollow curved portions 58 and 59 for preserving adjusted cocoons are formed; and on the wall 51 of the hollow curved portion 58 and 59, several projections 66 for hanging threads are formed at intervals. 0n one side of the hollow curved portion 58 a. hollow pot 6| for catching thread ends, is formed and at the same time, proper heating arrangement, such as an injection pipe 62 is provided.

On the other side of the curved basin 58, a libre adjusting curved basin 83 is formed; and its bottom is connected to the bottom of the fibre end catching basin 6| by a connection pipe 64, a water basin 65 being provided at its middle portion, so as to automatically regulate water levels of the fibre catching and bre adjusting basins; the bottom of the fibre adjusting basin 63 is connected to the bottom of the water tank 56 by means of a conduit 68 (Fig. 2) and in the ilbre catching basin 6| and the fibre adjusting basin 63, a cocoon basket as indicated by 61 and Fig. 1 and Fig. 3 is adapted to be suspended alternately. On one -side of other curved hollow pan, a dropped cocoon storage basin 68 is formed and its bottom is drilled with drainage holes 69. On the other side of the curved hollow pan, boiled cocoon storage basin 16 is provided and drainage holes are formed at its bottom.

The boiled cocoon storage basin 16 and dropped cocoon storage basin 68, are formed within one common wall; and from boiled cocoon storage basin to the edge ofdropped coccoon storage basin, the bottom face gradually slopes up, thus making it convenient to take up boiled cocoons for general reeling operation.

On one side of boiled cocoon storage 16 an inferior cocoon storage 12, waste storage 13 and crysalis storage 14 basins are provided side by side; drainage h oles 15 being bored at bottom of each basin.

Now to explain the pipe arrangement of the reeing pan, main pipe 16 is horizontally laid in the lower part of machine frame and from the main pipe 16 a connection pipe 11 branches oil', which branches again into two separatev pipes, which supply a small amount of water constantly, are turned down into the water tank 56 of reeling pans 4 and 6 provided at both sides of column 3, correspondingly situated.

From the upper part of main pipe 16, connection pipes 82 and 83 branch oil.' and terminate at the fibre end catching basins of reeling pans 4 and 6.

At the ends of these branch pipes, outlets 34 and 85 are fitted so as to be able to turn round freely; and through cocks provided at appropriate situations, a large amount of water may be supplied to the libre catching pot 6| and the water tank 56, according to the amount needed.

Connection pipes 86 and 81 are iitted to the drainage holes 69 and 1| of dropped coccoon storage 68 and boiled cocoon storage basins 16. 'Ihrough cocks 88 and 89, these pipes drain into gutters 96 and 9| horizontally laid under reeling pans 4 and 5.

Fromthe gutters 96 and 9| water is drained olf, by means of drainage pipes 92 and 93.

Above the water main 16, a steam main pipe 94 is horizontally laid and branches oil' into pipes 95 and 96; and through valves 91 and 98, these branches are connected to the steam heating pipe 82.

From the bottom of Ithe water tank 85 provided midway between the libre end catching pot 8| and the ilbre adjusting basin 83, a drainage pipe |66 tltted with a cock 99, is connected; its end runs into receiving gutter and drains of! water as much as required.

Thus in the reeling pan tted with steam pipes, water pipes and drainage pipes, fibres from cocoons |6| retained in water tank 58, will go through rotary feeding apparatus, up to spools 48, as will be explained later.

'I'he rotary feeding'devices |62 are provided side by side in base plate |63, the number of these devices being the same as that of spools.

As indicated in Fig. 9 and Fig. 10, in each rotary feeding device |62, the upper portion of a thread passage tubular axle |64 passes through the forward edge of a base plate |63, being screw connected thereat, and depending therefrom. An vaxial hole |66 is drilled through the axle |64 for passage of threads. In the lower portion of the thread pasage hole 66, female screw threads are cut, and a flanged body 88 is threaded therein. A transmission wheel |69 loosely iits on the axle 64 and its lower portion is retained in position by the flanged body |68 so as to be free to revolve. In the rim of the transmission, wheel |09, a V-shaped channel is formed; and in the channel, several water holes are bored. These holes communicate with the clearance space ||2 provided within transmission wheel |09. The lower part of transmission wheel |09 has a cylindrical shape I I3 and around the cylindrical part a groove ||4 is cut to receive embracing bars ||5 and ||5, these bars being fitted so as to be easily detachable.

The embracing bars ||5 and ||5 consist of two metal members which are bent in their middle portions into semi-circular shape ||1 so as to` embrace the flanged body; and the straight portions are fastened together by soldering or some other means. In each of the V-shaped grooves I l0, a belt ||8 is adapted to run. Each belt runs over the grooved pulleys ||9 and |20 fitted on both ends of the base plate |03. Each -of the belt pulleys |20 operates through a transmission mechanism |2| and transmission belt |22; transmission beltl |22 being operated by means of a grooved pulley |23 fixed to the main shaft 5.

Above the rotary feeding devices thus formed, fibre collecting devices |24, numbering the same as the feeding apparatus, are provided.

In each fibre collecting device, an arrangement to stop the spools is provided. To explain the construction of the fibre collecting device and operation of the spool stopping arrangement reference is had to Fig. i1 and Fig. 12. lA supporting piece |25 is formed above the base plate |03; and the top thereof is formed into a bent plate |21 having a hole |25. Adjoining the hole, a slot |25 is cut through the plate and under feeding devices |02 are moistened at their ends vided in the connection pipe and at an appropriate situation of steammain 94, a drainpipe |41 fitted with cock |45 is provided and drains of! water condensed in the steam pipes.

The belt ||5 held stretched against the rotary with water coming from water pipes |40 and |49 which are connected to the pipes 1l connected to the water main 15.

In Fig. 3, |50 and |5| show kennel devices engaging with the thread guide wheels |31' and and 52 and |53 are threads to wind round reeling spools, through rotary feeding devices |02 and the thread collecting device |24.

In the operation of the present invention, by an appropriate means, boiled cocoons are taken to boiled cocoon storage basin 10; then utilizing the sloping plane of bottom of the basin, a proper amount of cocoons adjusted by catching the fibre ends, is preserved in the projections 50 and at the same time, made to float in the water tank 55 provided under the rotary feeding device; fibres coming off from the cocoons are made to pass through the passage hole |05 of rotary feeding devices |02; and through the thread collecting member |3| of the thread collecting device |24, the fibres are assembled by means of "kennel device and through the thread guides of 'the rocking bar 44, made to wind round the spools 48. l

After these preparations are completed, the

lentire machine is operated; those cocoons reserved at curved parts and 59 by means of the bent plate a lever |29 is fitted on an axle |30, the end oi' which forms fibre collecting member |3|. On the other end of lever |29, a projection piece |32 is formed; and to the 'axle |30 a thread guiding wheel |33 is fitted.V A reciprocating rod |35, fitted with engaging projection |34 is inserted in the hole |25. The lower end of the projection |34, rests on the projection |32 of the lever |29; and to the lower end of sustaining plate |25, a lever |35 is fastened and made capable of pushing up the vertical reciprocating bar |35. In the middle portion of the reciprocating rod 35, a thread guiding wheel |31 is fixed, so as to move freely up and down, and the upper portion -of the rod is sustained by sustaining plate |35. At the upper end of the rod, a reel |40 fitted with pulley |39 is provided, so as to be free to perform up and down motion. .In the thread collecting device |24 thus formed and spool stopping arrangement, threads gradually coming up from rotary feeding devices, go round the spools through thread collecting member |3|. 'In lcase knots are formed in threads, they press against thread collecting device |24, causing lever |29 to tilt up about the axle |30; thus the reciprocating rod |35 sustained by the projection |32 of the lever |29 comes down; and pulley |39 connected to the rod also comes down, presses against the circumference 4| of the spool 45, and stops the rotation of the spool. When knots,

loops and nibs are removed, the lever |35 is oper- K projection 50, are gradually fed to rotary feeding devices; cocoons not adjusted at boiled cocoon storage basin, are taken to cocoon basket 51 suspended in the fibre catchingy member 5| and boiled; the cocoons, properly boiled there, are,7 transferred to the hollow pots 53 of the fibre adjusting member, being retained in baskets; cocoons whose fibre ends are adjusted, are suspended at projections 50 also and treated in.

similar manner as explained above; and cocoons whose fibres have broken, are taken: to the dropped cocoon storage 55. When a fair amount of cocoons has collected, the cocoons are taken to the hollow basin 6| of fibre end catching member and similarly treated there. Of the cocoons dropped into water tank 55, those which have fibre ends are directly supplied to the feed-.- ing devices and then fastened and fed for operation; in this way, cocoons to be fed to the rotary feeding devices are given constant temperature anduniform goods are produced.

The rotary feeding devices |02- operated by the belt ||8 are fed with water at the clearance hole ||2, the water being carried along with the running belt H5; and passing through the holes into the clearance hole. Thus the rotation of thread passage axle |04, is smoothly done by water lubrication; fastening and feeding are done and threads are sent up.

When the cocoon fibres have broken during Y fastening and feeding operations, the fibres are taken to the embracing rod ||5 and fastened there with other fibres.

In this way, fibres from rotary feeding devices pass to the rocking bar 44 from fibre collecting devices through kennel devices, where by the arrangement above explained, threads are moved to right and left and uniformly wound round spools 43. When knots, loops and nibs are formed, spools are automatically stopped 'by` operations above explained and winding ceases.

The present invention comprises the construction fully explained above by which multiple thread reeling is smoothly and emciently done at the same time; characteristic features of reeling pan, rotary fastening and feeding apparatus, automatic stopping arrangement of spools, reciprocating device of rocking bar due to special mechanism, spools provided so as to be detachable and to be operated independently by friction, spools or reeling pans and pipe arrangement for steam, water and drainage connected with them, al1 combine to produce goods of superior quality.
